What We Have Learned about the Universe from Low-Energy Neutrino Physics Experiments and NERSC’s Role in the Discoveries

Nuclear Science Division, Berkeley Lab

About the Speaker

Alan Poon is the program head for Fundamental Symmetries and Neutrinos and a senior physicist in the Nuclear Science Division at Berkeley Lab. He has been a NERSC user for over 20 years.

Abstract

NERSC is instrumental in discovering neutrino flavor transformation and various investigations of fundamental neutrino properties. These discoveries represent a paradigm shift in our understanding of neutrinos. They establish the massive nature of these elusive particles, contrary to their prescription in the Standard Model of Elementary Particles.

In this talk to commemorate NERSC’s 50th anniversary, I will discuss the neutrino discoveries it enabled in the golden era of neutrino physics in the previous three decades. These notable results include the resolution of the Solar Neutrino Problem and the discovery of neutrino flavor transformation by the Sudbury Neutrino Observatory, recognized in the 2015 Nobel Prize in Physics and the 2016 Breakthrough Prize in Fundamental Physics; the discovery of neutrino oscillations in reactor neutrinos and the measurement of terrestrial radiogenic heat production through geo-neutrinos by the KamLAND experiment, recognized in the same Breakthrough Prize that year; the investigations of whether neutrinos are their own antiparticles though a rare nuclear decay with a lifetime exceeding 12 orders of magnitude beyond the age of the Universe by the MAJORANA DEMONSTRATOR, LEGEND, and the CUORE experiments; and the most sensitive laboratory measurement of the neutrino mass by the KATRIN experiment.
